Sta-Kon RA18-38 Ring Terminal 3/8 in Stud 16 AWG 600 V Nylon

Sta-Kon RA18-38 16 AWG Ring Terminal

The Sta-Kon RA18-38 is a nylon-insulated ring terminal built for 16 AWG copper conductors. It accepts wire sizes from 22 AWG up to 16 AWG and is rated for 600 V. The 3/8 inch stud size suits automotive and industrial grounding or power distribution points. CSA certification and UL listing E9809 confirm compliance with North American safety standards.

Serrated barrel holds under vibration and heat

A serrated barrel grips the conductor tightly when crimped, maintaining contact integrity during sustained mechanical vibration. The nylon insulation withstands continuous operating temperatures up to 221 Degrees F without melting or becoming brittle. Tin-plated copper contacts resist oxidation over long service periods, preserving low resistance across the joint. Partial insulation coverage leaves the barrel visible for easy inspection of the crimp quality.

Red nylon sleeve identifies wire range at a glance

The red colour code signals the 18 to 22 AWG range to installers without reading fine print. A 0.53 inch tongue width and 0.35 inch hole spacing match standard 3/8 inch stud patterns on terminal blocks and bus bars. The 0.52 inch barrel length provides sufficient crimp area for a secure mechanical bond. Nylon material resists common automotive fluids and abrasion better than vinyl alternatives.
